Few industries are being disrupted as drastically as the retail industry. Pioneers of new business models, such as Alibaba and Amazon, are launching innovations in rapid succession, such as voice ordering and real-time pricing, while simultaneously building scale and driving down costs. More retail purchases are moving online, and a growing number of manufacturers now sell to consumers directly, cutting out retailers entirely. Making matters more challenging, these shifts are happening across practically every retail category – books, entertainment, housewares, clothing, food, financial services, and even energy.
